 Joyban  both  those  fish  are  denisoni  mate,  the  chala  is  different  again  in  it's  shape  position  of  the  mouth  and  the  solid  black  marking  in  the  dorsal  fin.

 I  second  that.  Dark  blotch  on  the  dorsal  is  a  distinct  difference.  Ofcourse  they  are  supposed  to  grow  much  larger  than  denisonii.
 
 BTW  its  spelt  Puntius  chalakudiensis.
 
 I  would  put  my  neck  out  and  say  this  pic  shows  the  difference  between  a  normal  denisonii  and  a  stressed  one.

 Hi,
 
 this  is  Heiko  Bleher  and  I  find  it  very  interesting  the  thread.  There  are  still  some  people  which  do  not  undertsnd  the  difference  between  the  two  similar  species  (and  other  who  do  not  want  to  see  it...).
 
 Those  2  pictures  sghown  here  are  correctly  identified  and  the  lower  is  P.  chalakkudiensis  and  the  upper  P.  denisonii.
 
 It  is  quite  easy  (and  possible  to  see  well  on  those  two  photos):
 1.  P.  denisonii  is  always  bright  red  (the  stripe  and  around  mouth)  vs.  chalakkudiensis  hardly  ever  bright  red  striped  -  as  seen  here.
 2.  P.  denisonii  has  a  bright  red  dorsal  fin  WITHOUT  black  in  it  vs  chalakkudiensis  has  a  black  mark  (not  really  a  spot)  in  the  dorsal  fin,  which  is  mostly  in  the  former  rays  and  upper  part  of  the  dorsal  fin,  and  the  same  has  hardly  reddisch  colours  (as  seen  here  in  the  lower  pictures).
 3.  P.  chlakkudiensis  is  always  more  blend  and  tail  colours  are  different  from  the  P.  denisonii,  and  bigger  (the  tail),  as  seen  here.
 4.  And  as  mentioned  here  already,  P.  chalakkudiensis  grows  much  larger  than  P.  denisonii  and  the  former  is  ONLY  found  in  the  Chalakkudy  river.
 
 Best  regards  from  a  collector,

 I  really  doubt,  apart  from  the  Black  blotch  and  size  of  fish,  if  anything  else  is  written  in  the  Key  to  the  species'.

 Hi,
 
 I  will  not  comment  on  this  issue  anymore,  if  anyone  has  his  doubt  than  it  may  be  so  for  his  own  sake.  For  the  scientific  community  and  its  description  these  are  the  two  species,  as  shown  here  and  what  I  mentioned  are  the  characters  which  are  visible  and  for  any  layman  to  destinguish  the  two  visually  (there  are  many  more  but  those  only  under  the  microscope.
 
 You  all  have  a  good  day.

 There  is  no  fish  called  Puntius  denisonii  chalakkudiensis.   I  hope  you  know  the  meaning  of  it  when  it  is  written  in  such  form.   It  means  the  later  is  a  sub-species  of  the  former.   denisonii  and  chalakkudiensis  are  two  different  species.

 i'm  afraid  i  still  have  to  dissagree  with  Heiko  on  the  two  pics,  having  seen  the  chala  and  plenty  of  denisoni  i  can  tell  which  species  is  in  the  tank  at  a  distance.

 Hi  Mr  Mickthefish,,
 
 have  you  been  to  the  Chalakkudy  river  and  collected  the  endemic  Puntius  there?  I  would  like  to  know.  As  I  was  there  3  times  and  also  in  all  the  other  known  habitats  of  P.  denisonii.  If  you  have  done  this  as  well  and  seen  the  fish  in  the  wild  and  taken  it  to  aquaria  (from  the  type  locality)  and  studied  it  from  those  type  locality,  than  I  am  willing  to  argue  with  you  further  in  the  UK,  otherwise  do  not  waste  your,  nor  any  one  elses,  time.
